Earlier this month, the agency scrubbed its second attempt because of a hydrogen leak.

NASA still needs to make sure those repairs worked, and the agency must also resolve an issue involving the certification of the SLS rocket’s flight termination system.

NASA teams have replaced the seals on the SLS rocket’s core stage that were associated with a liquid hydrogen leak that forced the scrub of the agency’s second Artemis I launch attempt.

Next up is a tanking demonstration to check the new seals under cryogenic, or super-cold, conditions. That could happen as early as the weekend.

NASA is still eyeing a third launch attempt for the first integrated flight of the SLS rocket and Orion spacecraft before the end of the month.

But there’s another hurdle.

Without a waiver, NASA will have to roll the SLS and Orion back to the Vehicle Assembly Building to rectify the rocket’s flight termination system by making sure the system’s batteries are properly charged.
